The multi-core tube consists of one to nine stainless steel tubes laid up spirally inside an extruded outer PVC sheath. For easy identification and protection purposes each individual tube is PVC sheathed in a different color. The extruded outer sheath is made of oil and seawater resistant, weatherproof, flame retardant, corrosion and acid resistant PVC.

The multi-core tube consists of one to nine stainless steel tubes laid up spirally inside an extruded outer PVC sheath. For easy identification and protection purposes each individual tube is PVC sheathed in a different color. The extruded outer sheath is made of oil and seawater resistant, weatherproof, flame retardant, corrosion and acid resistant PVC. The multi-core tube (outer sheath) is continuously marked at every one meter throughout the entire length for easy installation. Heat shrinkable products provide complete water sealing, abrasion and corrosion protection under all conditions.
